Active Transport in Plant Root Cells Requires That Those Cells

Multiple Choice

Active transport in plant root cells requires that those cells have access to O₂. Normally there is enough O₂available in air pockets in the soil, but flooded soil has very little O₂. Thus, unless they have special adaptations, plants in flooded soil effectively have no active transport in their roots. Which of the following should you expect to occur for trees without special adaptations to flooding after several days in flooded soil?

A) excess uptake of water and minerals in the xylem only
B) wilting of their leaves
C) bursting of leaf cells due to excess water flow
D) excess water pushed out at the margins of their leaves only
E) excess uptake of water and minerals in the xylem, and excess water pushed out at the margins of their leaves
